Regulatory changes boost energy storage in three major regions in Spain

The Spanish regions of Andalusia, Galicia, and Valencia, have approved regulatory modifications designed to fast-track the administrative processing of energy storage projects. The measures cover both storage systems co-located with renewable generation and smaller stand-alone facilities. These initiatives aim to cut development timelines and regulatory red tape, thereby facilitating renewable energy integration and strengthening grid flexibility.

In Andalusia, Law 4/2025 of Dec. 15 establishes an “urgent” processing pathway for co-located storage projects falling under regional jurisdiction, provided they are not subject to an environmental impact assessment (EIA). These procedures will adhere to Royal Decree 1955/2000, allowing developers to submit their application and execution project simultaneously. Additionally, the public information and consultation periods for affected administrations and agencies are reduced by half. This goal is to accelerate the commissioning of battery infrastructure.

The Valencian Community has approved Decree Law 14/2025 of Dec. 26, again introducing urgent measures for administrative simplification and regulatory clarity. Key changes include a modified authorization regime for stand-alone storage facilities under 10 MW, and the explicit adoption of the state framework for hybridizing storage with generation assets that have already undergone environmental evaluation. The decree also establishes urgent processing for projects exempt from ordinary environmental assessment. The decree law is currently awaiting parliamentary ratification.

In Galicia, Law 5/2025 of Dec. 23 on fiscal and administrative measures amends the Galician Land Law to permit energy storage projects on rural land, provided they do not involve urbanization or land transformation. This modification offers greater legal certainty and and eliminates one of the main barriers to the development of this type of facility in rural areas.
